Hi, If you are getting the “Moisture has been detected” warning, it’s doesn’t mean that your Samsung phone was in direct contact with water. Most of the time, the charging error might be caused by a very humid atmosphere and sweating if you live in a hot area. The presence of dirt in the USB port of your Samsung device might also cause charging issues.
If you are having problems with charging your Samsung Galaxy smartphone, it may be due to one of the following reasons:
- The charging port is wet or it has moisture residuals.
- Dust particles have build up inside the USB port.
- The charging port has been damaged due to corrosion, or the use of incompatible charging accessories.
Use a soft dry cloth to gently wipe your Samsung phone and shake it while keeping the charging port down. Then place it in the open air or under the ceiling fan for some time so that the moisture evaporates.
Please try using a different USB C Type C cable to charge your phone. Doing so will rule out the possibility of a damaged USB port. If the moisture detected bug has disappeared, it’s time to get a new charging cable.
Boot into the Safe Mode: Safe Mode is a diagnostic tool for Android devices. If you noticed that you started getting the “Moisture has been detected” warning right after installing an app, this tip might help you. A rouge 3rd-party app might trigger serious problems including the moisture bug. Reboot your Samsung device into the Safe Mode and plug in the charging cable. If you no longer get the moisture detected error, it means the real culprit is some recently installed app. You can uninstall the suspicious apps one by one in the Safe Mode and fix the charging issue.
If still the issue persists try to visit the Samsung authorized service center by the link given below to get it fixed.
- Power off your phone
- Press and hold vol up and power key until you are in recovery mode

- select Wipe Cache Partition
- press power key to confirm
- click yes

I have this same issue on 2 Samsung phones. S20+ and now S23 Galaxy Ultra. I literally plugged my phone IN to install the update and post update it was warning me to unplug because of moisture or foreign material in the charging port. I believe this is a BUG that has been introduced by the latest OS update. Have you had any luck resolving this?
